It is football's Everest, Olympic gold, Oscar - the pinnacle of a player's career.

In June, Kane expressed his desire to join an elite group that includes Sir Bobby Charlton, Johan Cruyff, Franz Beckenbauer, Ronaldo and Lionel Messi.

"I'd do whatever I can to win that big gold trophy. It is definitely something I aspire to do," he said.

"Cristiano Ronaldo won La Liga and the Champions League and that is why he wins it. Messi is in a similar situation.

"To do that it isn't just individual, it is about a team winning trophies and, hopefully, that is what I can do at Tottenham."

That poses the question...

Does he need to leave Spurs to become the best?

Mauricio Pochettino salutes 'great striker' Harry Kane on 100th goal

Goals for Tottenham: 103. Trophies: 0.

Former Manchester United and Everton defender Phil Neville said Kane, 24, may have to move to claim more team and individual honours.

"He could have to leave Spurs to become that top, top, world-class Robert Lewandowski-type player," said Neville.

"If they maintain being a top-four team, that will not be good enough for Harry Kane.

"He needs to be challenging for Ballons d'Or. He needs to be challenging for Champions Leagues and if Spurs are always going to be that 'nearly team', eventually he will want to leave and join a Real Madrid or a Barcelona.

"There will always be a doubt about Harry Kane until he gets to that level."

Kyle Walker left Tottenham for Manchester City this summer in order to "win a trophy", while fellow full-back Danny Rose suggested in August he might leave because of Spurs' perceived lack of transfer activity.

According to Neville, Tottenham may need to end their nine-year barren run without a trophy soon if they are to hold on to Kane.

What is Kane worth in today's market?

If Tottenham decide to sell their prize asset, what sum could they get?

According to the International Centre for Sports Studies' transfer value widget, Kane is now valued at 170.2m euros (£153.5m) - up 10.8% from the figure in June.

He has scored more than 30 goals for club and country combined in each of the past three seasons and his Spurs contract expires in 2022.

If he continues scoring at his current rate, his value could be even higher by the end of this campaign.
